Specification forming part of Letters Patent No. 193, I 95, dated July 17, 1877; application filed April 30, 1877. V

To all whom it may concern:

Be it. known that I, CALVIN T. STEOKEL, of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Folding Shutter. of which the following is a specification:

In the accompanying drawing, Figure 1 represents a front elevation of my improved folding shutter, shown in closed position and Fig. 2 is a vertical transverse section of the window-casing, showing the shutter thrown open and its slats in folded position.

Similar letters of reference indicate corresponding parts.

This invention is intended as a substitute for the fixed iron gratings or bars in basement, store, and other windows, so as to provide a shutter that may be folded and turned, making the room more cheerful, and facilitating the cleaning of the windows, 860., while combining, when locked, the same degree of safety as the bars.

The invention will first be described in con nection with the drawing, and then pointed out in the claim.

The shutter-sections are retained by end bars and top and bottom guide-stops of the window-casing, and then looked in this posifolded into small space, or opened to extend .of the other hinge slides at the same time in a guide-slot, a, of the same, so as to admit the folding or turning to the outside or inside, according as the shutter is arranged at the outside or inside of the window. The other end of the shutter is provided with an upright bar, B, to which the cross-bars are pivoted, and which slides, by end projections b, into recessed top and bottom guide plates or stops d of the casing, so as to hold the shutter in closed position, as shown in Fig. 1, and admit the locking of the upright bar or bars by a padlock, or any other suitable locking device. The folding shutter is bu rglar-proot', furnish ing the same protection as the fixed grating, but giving, in addition thereto, the great convenience of opening them during the day, and presenting a neater appearance without the objectionable features of the rigid bars.

Having thus described my invention, I-

claim as new and desire to secure by Letters Patent- CALVIN T. STEGKEL.
